Troubleshooting the Fan Assembly
To isolate a fan assembly problem, follow these steps:
Step 1
Step 2
Verify that the FAN LED on the fan assembly is green.
If the FAN LED is not green, see the “Solving Problems at the System Component Level” section on
page E-2 to determine whether or not the power subsystem is functioning properly.
Check to determine if the FAN LED is red. If the FAN LED is red, the fan assembly is not seated in the
backplane or has malfunctioned.
Do the following:
• To ensure that the fan assembly is seated properly, loosen the captive installation screws, remove the
fan assembly, and reinstall it.
• Tighten all captive installation screws, and then restart the system.
• If the FAN LED is still red, the system detects an individual fan failure. Contact a customer service
representative for instructions.
Troubleshooting Modules
To isolate a supervisor engine or switching module problem, follow these steps:
Step 1
Step 2
Verify that all status LEDs are on.
If any status LEDs on the supervisor engine or any switching modules are red or off, the module might
have shifted out of its slot. Reseat the module until both ejector levers are at right angles to the rear of
the chassis. Tighten the captive installation screws at the left and right of the module front panel, and
restart the system.
STATUS LED Indications
The STATUS LEDs can indicate two alarm types: major and minor. Major alarms indicate a critical
problem that could lead to the system being shut down. Minor alarms are for informational purposes
only, giving you notice of a problem that could turn critical if corrective action is not taken.
When the system has an alarm (major or minor) that indicates an overtemperature condition, the alarm
is not canceled and no action is taken (such as a module reset or a shutdown) for 5 minutes. If the
temperature falls 5°C (41°F) below the alarm threshold during this period, the alarm is canceled.
Table E-1 lists the environmental indicators for the supervisor engine and switching modules.
Note
Refer to the Catalyst 6500 Series Switch Module Installation Guide for additional information on LEDs,
including the supervisor engine SYSTEM LED.
